  1. Not a fan of Flatpaks, but this is a sweet app. I’ve missed Google Sketch under Linux (could never get it to work under wine) and BricsCAD isn’t as intuitive, but Sweet Home is great. I was able to whip up a floor plan in no time.

  2. i have been success install Sweet Home 3D under terminal, but
    How to launch Sweet Home 3D, because there is no in “Show Applications”

    Thank you
